Earth's formation remains a strange, scientific mystery. We live on a planet in a solar system with seven other planets and have discovered thousands of exoplanets to date. But how planets like Earth form still remains a subject of great debate. Currently, there are two leading theories on...
The other, newer theory suggests that planets form by gathering millimeter-sized "pebbles" from the outer solar system drifting towards the Sun through a process known as accretion, condensing it all together through gravity to form these planetary embryos that would form the planet. Were the plan...
Hubble used the light curves of the Cepheid variables to measure their distances from Earth and found that they were much farther away than the known limits of the Milky Way. Therefore, these spiral nebulae were indeed other galaxies outside our own. There are still many mysteries surrounding ...
Why did rocky planets form closer to the sun and the gas giants farther away? One theory involves the solar wind, the steady flow of plasma that emanates from a star. When the sun first came into being, this wind was far stronger than it is today -- strong enough to blast lighter el...
, but none so young as this. the slightly older one has been christened k2-33b; the younger, v830 tau. scientists can use them to study how planets form, which in turn can help us better understand how the earth formed, and thus how life might potentially form on other planets...
Earth was cold. Only gradually did it heat up, in this view, as uranium and other radioactive elements embedded in its rock decayed and released heat;only gradually did the heat drive water vapor, which had attached itself to rocky minerals in the solar nebula, out of Earth's interior. ...

2. Did you learn art at school when you were a child? Yes. We did had an arts subject during our school days and we were taught lot of basic things like how to color, shade or different kinds of paintings. No, I did not. In our school, there was a choice between arts and music...
About 70 percent of our planet’s surface is covered with water, and it plays an important role in our daily lives. But how did water get on Earth in the first place?
